Windows FAQ: Answers to Common Replacement Window & New Install Questions

How do I know it’s time to replace my windows? 

Signs include drafts, fogging or condensation between panes, difficulty opening or closing, visible damage to frames, or rising energy bills. In Louisiana’s hot, humid climate, wood and low-quality vinyl windows often warp or rot faster. If your windows are more than 15–20 years old, an inspection can help determine if replacement is the smarter investment. 

What are the benefits of new windows for Louisiana homes? 

• Energy savings from modern Low-E glass and insulated vinyl frames. 
• Storm protection with impact-rated options that meet or exceed Florida Building Code (FBC) standards. 
• Curb appeal with custom colors and styles to match your home. 
• Increased resale value. Replacement windows are a proven home improvement ROI. 
• Peace of mind with LAS’s lifetime warranty coverage. 

What is the average cost of replacement windows? 

Costs vary depending on size, style, impact rating, and customization. On average, Gulf South homeowners spend $600–$1,200 per window installed. LAS provides free estimates, so you’ll know exactly what your project will cost before moving forward. 

Can windows be replaced during summer or hurricane season? 

We schedule window replacements in every season, including summer and hurricane months, because that’s when many homeowners prioritize storm prep and energy savings. Learn more about our replacement window installation process. 

What's the difference between new construction and replacement windows? 

Replacement windows are custom-built to fit into existing openings without removing siding or trim—perfect for upgrades and energy retrofits. New construction windows, on the other hand, are installed when a home is being built or during major remodels where walls are exposed. Replacement windows are the right choice for most Louisiana homeowners looking to improve efficiency and comfort without extensive renovation. 

What’s the difference between vinyl, wood, aluminum, and fiberglass windows? 

• Vinyl: Durable, cost-effective, and resistant to rot and corrosion. Best suited for Louisiana’s humid climate. 
• Wood: Wood may look traditional, but in Louisiana’s climate it requires constant upkeep to fight rot and swelling. For a full breakdown, see our Wood vs Vinyl Windows guide. 
• Aluminum: Strong but conducts heat, leading to higher energy bills. 
• Fiberglass: Stable but 2–3x more expensive than vinyl and has weaker corner connections 

Why does LAS only use vinyl frames in our region? 

Because vinyl consistently outperforms wood, fiberglass, and aluminum in hot, wet climates. LAS vinyl windows: 

• Resist moisture and humidity. 
• Provide excellent insulation against heat transfer. 
• Are easy to maintain and long-lasting. 

What window styles are available? 

LAS custom manufactures: 

1. Single Hung 
2. Double Hung 
3. Casement 
4. Horizontal Slider 
5. Picture & Fixed Windows 
6. Sliding Glass Doors 

Every window is custom measured to the exact dimensions of your home’s openings, ensuring a seamless fit instead of forcing a stock size. 

What does ENERGY STAR® rating mean? 

It indicates windows meet strict performance standards for insulation and heat gain. LAS windows exceed ENERGY STAR requirements for the Southern Region. 

What is Solar Heat Gain Coefficient (SHGC), and why is it important in Louisiana? 

SHGC measures how much solar heat enters your home through the glass. In Louisiana’s climate, the lower the SHGC, the better. This helps to reduce cooling costs during long, hot summers. LAS windows achieve SHGC values as low as 0.16. 

Do argon gas and Low-E coatings make a difference? 

Yes. Argon gas between panes insulates against heat transfer, while Low-E coatings block UV rays and infrared heat. Together, they keep interiors cooler and protect furnishings from fading. 

How much can new windows reduce my energy bills? 

Savings depend on your home’s size and condition, but most LAS customers see 10–30% reductions in monthly energy costs after upgrading. 

What is a DP rating and why does it matter in hurricane zones? 

Design Pressure (DP) measures a window’s ability to withstand wind and water. Some types of LAS windows are tested up to DP90 (230 mph winds), exceeding local building requirements. 

Are impact windows better than shutters? 

Impact windows provide permanent storm protection without the need to install shutters before each storm. Many homeowners choose a combination of LAS impact windows and shutters for maximum protection and flexibility. 

Are LAS windows FBC rated? 

Yes. LAS impact windows and shutters are tested to meet or exceed Florida Building Code standards for impact resistance. 

Why does installation matter as much as the window itself? 

Even the strongest window can fail if poorly installed. Proper installation prevents leaks, air gaps, and structural issues. 

Who installs LAS windows? 

Our installers are LAS-trained employees, not subcontractors. They follow OSI Installation Masters™ standards to ensure long-term performance. 

What warranties are included with LAS windows? 

LAS stands behind every window we manufacture and install: 

1. Lifetime limited warranty on vinyl frames. 
2. Lifetime limited warranty on insulated glass. 
3. Five-year labor warranty on installation. 

Full warranty details are available with your estimate package or by request. 

Can I customize the color and style of my windows? 

Yes. LAS offers a variety of standard and custom colors, grid patterns, glass options, and hardware finishes. 

Do windows affect home resale value? 

Absolutely. New windows are one of the smartest upgrades, often recouping a large portion of the investment at resale. Energy-efficient upgrades are especially appealing in the Gulf South, where energy costs are high. 

Who do I call if I need service after installation? 

You call LAS directly. Unlike competitors who outsource sales, manufacturing, and installation, LAS handles the entire process in-house, so you’ll never get the runaround. 

How long will my windows last? 

With proper care, LAS vinyl windows are designed to last 25+ years in Gulf South conditions. 

 What kind of maintenance do vinyl windows need? 

Minimal. Just clean glass and frames with mild soap and water as needed and ensure your weepholes are unobstructed annually. Unlike wood, vinyl won’t need painting, sealing, or sanding. 

When it comes to energy efficiency, storm protection, and long-term value, LAS windows are built for our Gulf South climate. From custom sizing to professional installation, we manage the entire process—and back it with trusted warranties.
